APPLICATION GUIDE

Pipe Materials for High-Temperature Steam

Material selection depends on design temperature, pressure, creep requirements and the governing piping or boiler code. Carbon steel may suit moderate conditions; Cr-Mo alloy families are considered as temperature and design demands increase.

Materials for Seawater and Chloride Piping

Chloride concentration, temperature, flow, oxygen, crevices and fabrication quality control pitting and stress-corrosion risk. 316L may suit limited conditions; duplex and super-duplex families are considered for more severe exposure.

APPLICATION GUIDE

Material Selection for Chemical Process Piping

Chemical compatibility is controlled by media, concentration, temperature, contaminants, pressure and whether the process is continuous or intermittent. Start with service data, then screen stainless, duplex and nickel-alloy families.

Stainless Piping for Food and Pharmaceutical Plants

304L and 316L are common starting families, but hygienic design also requires the correct surface finish, weld quality, cleanability, drainage, gasket material and documentation.

Bolting and Gasket Selection for Class 600 Flanges

The answer depends on flange material, facing, design temperature, service medium and applicable joint standard. Raised-face and RTJ assemblies use different gasket systems.

APPLICATION GUIDE

Carbon-Steel Piping for Low-Temperature Service

Standard carbon-steel grades are not automatically suitable below their permitted design temperature. Low-temperature carbon-steel families and impact testing may be required.

APPLICATION GUIDE

SS 304L vs SS 316L for Piping

Both are low-carbon austenitic stainless grades. 316L contains molybdenum and generally offers better resistance to pitting in chloride-bearing environments, while 304L is widely used for general corrosion-resistant fabrication.

Common Materials for Refinery Process Piping

Refinery systems use multiple material classes selected by fluid, temperature, pressure, corrosion mechanisms and process-unit specification. Carbon, Cr-Mo alloy and stainless families are frequent starting points.
